' TO ALL PERSONS TO` WHOM-*THESE PRESENTS SHALL'GOME:

VBe it known thnt I, Jesi-:rn 'lfm-1yr, of Millerton,inthe county' of Vl'utehes's, and State of New York, here, invented a Combined Self-Acting Coupling and {Dulfer-for Railway Cars; nnd'deherehy declare the some `s fully described and represented in the'l'el'lowing specification end the neeornpgnjing drawings, of whichl Figure 1 is a top view reprccn'tihg my invention ns v: ipplied to twmrailrohd trucks.

Figure (i representen fece viewv of one of the buffers, with its 'serowfnd sliding-bleek for xt etsiningtlre Selfoperating'catch in position. Y i b Fignre 7, it fece vien' representing the opposite butler, with' its screwrod and latch for maintaining the self# operating catch in pluee;and o Figure. 8, 4a Yiew representing' one of the trucks 4thrownotlfromfthe railroad track, und my Vinventionin the not of disengnging itself n nd disconnecting the trucks. I

This invention` relates' to a novel contrianee for coupling and disengngng railroad uears, in` 'which they coupling is self-acting, that is'to say, will engage itself, and when so engaged will. lie held in such position hy droppingu latch or hlocksgninst the foce of the catch or connecting-link holder; Vand when it is'd'esredto disf'. t engage the cars, thc bre'kemnnmerely mises. thel 'block or`lntclr,j\vhen the cars will be disengagefhwa'nd- -will' remain disengaged, und fwill noten gege themselves while standing oir-the trs;k(cs isthe colse with other definen) until the bleek or latch is ugainlourer'ed, and this performe'hco is accomplished by the'y hrakelnan, t hilelstan'ding on' the plutforxn of the ear, without resorting tothe dangerousl and often fetal expedientA of going between 'the trueksto perform tlie operetion.` Y l A Furthermore, should one or more eers, wliilein rapid motion, run ofi' the track, they will immediotely dis# .engage themselres Without the hill of the brakcrnan, as shown in iig. 8; and, besides' this, the strainer pressure* i caused by tho ears shutting against their hu'crs 'whenstarting or breking'np a train of carsis not sustained by the framework of tli'e'ears or trucks, asis usual in st tcl1.cases, hntb'y the bui'ef-bers`which abut against an' .India-rubber spring 'placed between' the -ex'trerne ends ofthe' buffer-hars; as shown in Eg. 3.

Having described the nature of my invention, I vwill noir. describe its'eonstrnction and mode of opration;

T In the drawiilgsf/L'A" represent two railroad trucks; B B', the buffers; b, the-'connecting-link'; G G, the

l i nk-eetches, whielrsning on 'pivots'e o in the buffer-mouths, snd'- sre so arranged as to maintain n vertical position bytheir own gravity. d l) D :tre the butler-hars, which are sustained by andslidc in snitshle bearing-s, d dfbelow the iloor of the trucks A A and between the braces a a oi' the some, 'ss shown in iig. 3. The seid buffer-liars have journals',V e c, on their outer 4ends for recerton of ther'hniers or buffer-months, and nuts or collars f f for the purpose of retaining the buffers B B in" position, while they (the buffers) revolve ontheir journals. G or G is the block or latch, which 'is' opernted'by the screw-rod H or H', and byiits agency the block G is lowered gsinst the fncelof the entch C, when it isdesired yto connect the coupling, and raised from 1 the catch -C when it is desiredtodisconnect the seme, as already explained.

Theoperation of my invention isv 'veryf simple,'and is'nsfollows; when it is desiredto-cdinectthe rail eers,

the hrnkenntn, -njhle tending on theplati'oiin of the car, lowers the'bloekor latch G by menus of the screwrod Il against the 'face ofthe linkcateher G, (the othcrhloeli G bcing'slicndy lowered, und the link b thereby held t A` in' position,) thesaid catchers beingnow in n position to receive und retaimthe link b, which, as the cars approach each other, seid' link wlll push thcJeil end o'f-jthe catcher C 'forwndftillthe cyc'of the link b posses seid tail end, `when the catcher w'ill'dropintothocyo ofthe linkLand prevent the release of' the'l'ink until the block or I 4 and while the cars are thuelmly connected together,

latch G is n'g'sin raised from the feccof "tlxece'tcher C;

should one or more oihte ,earsrun oli' the tra'ek while the train is in jrapid motion, the'conpling will, in -this case, disengnge itself, for the bu'ers, beingso arranged as to turn ontheir journals, one of the buffers-nil! onlyl require temake e qnarter turn, (in 'relationfto tho other,) when -theeatclrC or C. will vhe' moved ewayrom the block Gr or G', nnd'the conplingdisengeged, as -shownin lig. 8: Furthermore, in rcldtio'nto reni-oring-the-strain or pressure caused by the buffers nhuting against each other, in stm-ting or braking vup a train of curs, from the framework of the ears to the huilen-hers, it will be observed that the bui`er-b=irs l) D slide freely within their hearings'd d, and their inner ends `nl mtting against the Indie-rubber springs K K', the whoh` pressure is brought-to bear on the smid rubber springs, and thus removed from the framework of the ears.

From the above itwili be seen that I have lesigneii n. siulple and elliciont coupling, which will* be :t great saving' f expense as regards the weer and telnr, consequent on the strain and pressure of railway cnrs., ns well as a. saving of human life.

.Having described my invention, what I claim, und desire to secure by Letters Patent, isi-- The coinhination nml arrangement of the revolving buffers B B', buffer-bers D D', blocks G G'. springs l K. nnilrods H H', substantially as described for the purpose specified.

In testimony whereof l have hereunto set my signature.
